PORCH AND LAWN swine.

I Application filed February tee to wheel supported object is the provision of a light weight portable swing'of small size, having only one seat in the place My invention rela ofthe usual two seats facing each other.

Another object of my invention is the pro.- vision of a swing which is speclally adapted 'to be used on porches and particularly on the porches of small size. Another object is the provision of structural features whereby the swing is made as safeas it is possible for such a swing to be, so that there can be no danger of the tipping of the swing nor danger of injury to the limbs or fingers of'children or careless persons. I

Still another of my objects .is the provision of features whereby both sides of the swing are moved positively and in unison to thus add materially to the comfort of the occupants and to the life of the swing.

Having in View these objects and others which will be pointed out in the following description, I will now refer to the drawings,'in which 1 r a 1 Figure 1 is an end view of the swing. the covering being removed to disclose interior Figure 2 is a view in perspective of the supporting structure for the tracks.

Figure 3 is an illustration of a portion of the seat and of one of its supports.

Figure is a view in perspective of one of the end portions of the carriage on which the seat frame rides.

Figure 5 is a view partly in front 'eleva-f tion and partly in section of the right-hand end portion of the swing.

The framework of the swing including the support for the tracks is partlyshowir in Figure'2. this figure showing only the righthand portion which is duplicated at'the opposite end of the frame. It consists of two longitudinal beams and 11 connected tog'zjether by means of uprights 12, 18 and 14. The beam 10 projects beyond the uprights 12 and 14 andis braced thereto by means of the braces 15. The upright 13 projects above the beam 11 and is provided at its 1,119.27. SrialNo.165,137.

which are braced to the end portionsof the swing by means of the braces 18; Theframe includes also arcuate tracks 19 20 and 21,

the tracks 19and 20 being designed to supon port the seatand the track 21' being designed to support the footrest. Thetwo tracks 21. at opposite ends of the swing are secured togather by meansof the beams 22. All'of the tracks are secured to the frame by means of 65 spacers 23 which space the tracks from the frame. The three tracks are arcuate in form, the arcs being substantially ahke. "The' tracks 19 and, 21. are smooth but the track 20 is provided witha rack 2401 its inner 7o surface. It is my object to construct the frame largely of wood but therack 24 is preferably made from a suitable metal such as iron or steel. f v i The carriage is bestshown'in' Figures 1 7a and 4. It consists of two horizontal beams 25 supporting flanged rollers 26 and 27 between them. Depending from the beams 25 is a beam 28 which is securely braced to the-beams 25 by means of the braces 29. At so the lower end. of the upright 28 there is secured platform 30 by meansof a pivot 31. This platform has a depending member 32 carrying at its lower extremity a flanged. who e133 which is considerably smaller-in diameter than'thewheels 26 and 27. The opposite end members of the carriage, of

which only the right-hand end member is shown, are rigidly secured together by means of the beam 34:, and the shaft 35 unites the two wheels 27 in rigid relation. Likewise theplatformincludes floor members 36 connecting the two "end members and braced thereto as shown The flanges of thewh'eels i 26 and 32 are smooth but the flanges of the wheel '27 are. toothed. The toothed .inner fiangeof the, wheel 27 is designed to coact with the rack 24:. j i

The seat comprises an ordinary bench seat 37 having end members 38 as shown in Figure 3. Secured to the members ,38 are inverted tracks 39 and 40, these also being spaced by means of spacers 41. The tracks 39 and iOare arcuate in form, the .arcsbeing substantiallyidentical: with each other and with the arcs of the tracks 19, 20 and 21. Thetraclt 40 is provided with a rack 42 which is similar to thefraclr 24 of the track 20. The rack 42 is designed to cooperate with the outer toothed'flange of the wheel 27 whereas the rack 24: is adapted tocooper ate Wit-l1 the inner toothed flange of the wheel .27. When'the parts are in-position, the

bar 39 is also similarly elevated.

wheels 26 and 27 rest on the tracks 19 and 20 with their flanges overlyingthe, edges of the tracks and with a meshing of the'inner flange of the wheel 27' with the rackfl l. At

the same time the tracks 39 and 40 will bear against the upper surfaces of the wheels 26 and 27, the flanges of which preventthe seat vfrom jumping the track.

the weight of the occupant will slightly unbalance the seat .so that the seat has a tendency to tip. *The stop 16 is immediately above thefupper surface of the bar 39 but it does not contact with the u per surface during the main portion of tie stroke'of the seat At the time when the scat'becomes more or less'balanccd over a pair of the wheels or rollers 26 and 27, one of the upper rojections 39 of the upperedge of the ar 39 engages the stop 16 which permits the seat to continue its stroke but which preventsany tilting. The limit oftlie stroke is, of course, defined by the stops at the ends of the bar 39 as shown in Figures 1 and 3. \Vhen either'of these two stops engages thestop 16 the limit of movement has een reached, since these two stops are designed to positively engage the stop 16 at the limit of movement of the swing.

In order to prevent any accidents to children or others, the working parts of the swing are covered. A wall 43 isprovided at the'sides as shown in Figure 5 so as to make the tracks and rollers inaccessible. The top is also covered with a. top'wall 44, this top wall being secured to the seat frame to move therewith.

One of the primary objects of. the invention hasbeen to'make the swing as safe as it is possible to make such a swing, This has been accomplished and largely by means of the stop arrangements which prevent any. tilting-of the seat when the seat is in either its extreme forward or in its extreme rearward. position. The pinions 27 which are secured to the shaft 35 are also instrumental in increasing the safety of the swing.

hen the weight on the seat is not evenly I distributed, as when it is occupied by only one person sitting at one end of the bench, at torsional. effect is produced and the swing then has a slight tendency to turn on its vertical axis. The result of this might, of course, be that the seat left its tracks to the injury of the occupant and the damage of the swing. The pinions, however, hold the parts against turning movements about a vertical axis and the flanges on the rollers have a similar effect. The shaft 35 forces the pinions 27 to'move in unison and to thus. reduce the tendency toward any torsional movement of the swing.

The seat member moves at a rate which is A porch swing including a frame having a pair of arcuate racks at the sides thereof and having a pair ofarcuate tracks forward of saidarcuate racks and having also a-pair of arcuate tracks below and forward of said first named tra=fl-:s,a scat member having a rear shaft provided with a pairof pinions secured thereto for traveling on said arcuate racks, a pair of wheels supporting the forward portion of said seat member and adapted to travel in said first named tracks,

a foot rest platform pivotally secured at the LESTER COOK.
